TETERBORO — You might not be able to teach an old dog new tricks. But you can still teach them to trick-or-treat.

Animals came dressed as bumblebees, ladybugs, pumpkins — even cops and robbers — to the "Magical Pets on Parade" event at the Bergen County Animal Shelter in Teterboro Saturday afternoon.

The event was held in celebration of the shelter's new partnership with Merlin's Kids, a non-profit organization that helps match service dogs with disadvantaged families. Annie, a Bernese Mountain Dog raised at the facility, will soon be matched with a family in order to serve a child with autism or other special needs.

The shelter also offered a discounted rate for families hoping to adopt kittens as part of the event.
